Have finished rebuild of my matching numbers '68 cuda, BB car, with correct VIN number and codes stamped on tranny pad. Before painting, made note of three large yellow numbers painted near pad, seemingly-"113". Just learned that is supposed to be the last three digits of the part number for that application. I can't find a part number anywhere close to"113". This has to be the original tranny because of the VIN number, doesn't it? This car is late '68. As far as I can see- 1967 is #2892 042, 1968 is #2892 042, and 1969 is #3410 608. What am I doing wrong?
